ULTRASONIC THICKNESS GAUGE - A1207 (A1207C)
wearing. This replacement can be made by the operator himself and is described in the
item 7.3 of this manual.
The digital light-emitting diode display makes possible the application of the device in a
wide range of temperatures (from -30°C up to +50°C). The device should be switched on
right before the measurement. The power on condition of the device is indicated with four
strokes on the display or result of thickness readings or any other information on the
display.
The continuous operating time from the built-in accumulator is not less then 24 hours.
Recharging of the accumulator is made through the special plug [6] (Pic 1). Time of
charging is about 11 hours. It is also possible to work with the external power supply that
should be connected to the same plug.
For adjustment of the ultrasound velocity in testing material there is a button for choice
of ultrasound velocity [5] (Pic 1). Usually there are four most frequently used velocity
meanings for structural alloys are preset in the device.
5400 m/s
5950 m/s
6060 m/s
6300 m/s
Stainless Steel
Low-alloyed Steel
Steel 40Х13
Aluminium Alloy D16
For more exact adjustment of the ultrasound velocity for a particular material there are
three additional (hidden) buttons [10] in the device. These buttons are hidden behind
the front panel of the case (Pic 1). With these buttons you can set the meaning of
ultrasound velocity from 1000 up to 9000 m/s with a step of 10 m/s. These set-up buttons
allows the operator adjust the meanings of four saved velocity meanings under his own
testing materials and then choose them already with external button of velocity choice.
Besides with the help of these additional buttons the operator can also set the following
parameters:
•
•
•
•
Time interval, that compensates signal’s delay time in prisms of ultrasonic probe;
The lower limit of measuring thickness range;
Contrast level of the display;
Dimension of the testing readings (metric or English).
All the set characteristics of the thickness gauge are saved after turning off the device
and at empty accumulators.
There are also finger holders on the device’s case that stop fingers when measuring,
special clip for wearing the device on the clothes and a cap that has two purposes at the
same time:
•
•
It protects the surface of the probe from damaging during transportation and
storage.
It efficiently covers the probe’s surface with contact liquid.
